Creating Your First Annotated Dataset

Text Annotation with Ollama

Step-by-Step Annotation Process:

1. Prepare Your Data: Start by gathering the text data you wish to annotate. Formats can include text files, spreadsheets, or any structured documents.
2. Choosing a Model: Decide which Ollama model you will use based on your project's complexity. For simple annotations, models like Llama 3 can be adequate.
3. Annotating Text: Using the Ollama API, set up a chat model that helps generate annotations based on human input. Here’s a quick code snippet:
   1 2 3 4 5 6 7 8 9 10 11 python import requests base_url = 'http://localhost:11434/api/chat' data = { 'model': 'llama3.1', 'messages': [ {'role': 'user', 'content': 'Annotate this text: <your_text_here>'} ] } response = requests.post(base_url, json=data) print(response.json())
4. Storing Annotations: After annotating, save your annotations in structured formats like JSON or CSV for easy retrieval and processing in the future.

Categorization & Labeling with Ollama

Implementing Categorization:

1. Define Categories: Determine the categories or tags based on the specific needs of your project. For instance, if you're working on sentiment analysis, your categories might include positive, negative, or neutral.
2. Interactive Annotation Process: Leverage interactive features within Ollama. You can create an interface where users can select the category as they read through the documents:
   1 2 3 python categories = ['Positive', 'Negative', 'Neutral'] selected_category = input(f'Select category {categories}: ')
3. Batch Processing: If you have a large dataset, consider using batch processing to maximize efficiency. Use scripts that iterate through your files, prompting the model for each item.
4. Exporting Annotated Data: Make sure to export your annotated data in a reusable format for training your ML models later.
